Northwest folk songs are mainly Xintianyou and Qinqiang, **** the same point is high-pitched, strong, there is a strong Northwest simple and naive mood. Strong rhythm and staccato is easier to infect others, even in the nine pits and eighteen ravines of the Northwest can be heard from afar.
The rhythm is free, simple and generous, high and long. The structure of the stanzas is very special, generally two lines per stanza, two lines with one rhyme, and the next stanza may or may not change the rhyme. The first stanza starts the poem and compares it with the next stanza, and the next stanza makes a point. A short song may have only one stanza, while a long one may have dozens or even hundreds of stanzas in succession. The rhythms of Xin Tian You are mostly very free, and the melody is unrestrained, open, and heart-wrenching.
Expanded:
There are two types of melodies: those with free rhythms, high and expansive melodies, and large ups and downs; and those with neat rhythms, strict structures, smooth melodies, and more delicate expressions of feelings. Albatross is a heirloom masterpiece engraved on the Loess Plateau in Northwest China with the old stiletto, and it is an oddball between the yellow slopes and the yellow water. A song, loud clouds, all sweeping sound; a sound into the ear, stirring, people's spirit is a revitalization.
